bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 WRTD: Data EEPROM Write Protection bit
1 = Data EEPROM not write-protected
0 = Data EEPROM write-protected
bit 6 WRTB: Boot Block Write Protection bit
1 = Boot block (000000-007FFF, 000FFF or 001FFFh
(1)
) not write-protected
0 = Boot block (000000-007FFF, 000FFF or 001FFFh
(1)
) write-protected
bit 5 WRTC: Configuration Register Write Protection bit
(2)
1 = Configuration registers (300000-3000FFh) not write-protected
0 = Configuration registers (300000-3000FFh) write-protected
bit 4-0 Unimplemented: Read as ‘0’
Note 1: Boot block size is determined by the BBSIZ<1:0> bits in CONFIG4L.
2: This bit is read-only in normal execution mode; it can be written only in Program mode.
